Regulators Approve PNM IRP Despite Staff Criticism

New Mexico regulators have voted to accept Public Service Company of New Mexico’s 2023 integrated resource plan, despite concerns about an escalation in costs and resources since the utility’s 2020 IRP. 

The New Mexico Public Regulation Commission (PRC) voted 3-0 on April 4 to accept PNM’s IRP — even though PRC utility division staff had several criticisms of the plan, including its “incredibly expensive” capacity additions. 

PNM could reduce costs by keeping two gas peaker plants in its resource mix for longer than proposed, staff said. 

Commissioners noted that their approval of the IRP was “narrow,” merely finding that the document’s statement of need and action plan were compliant with IRP rules. The vote did not approve resource acquisitions or costs or determine prudency, steps that will come later. 

“Staff brought up some extremely important points,” Commission Chair Pat O’Connell said before the vote. 

PNM said in its plan that the 2023 IRP “lays out an aggressive plan to achieve a carbon-free portfolio by 2040.” 

“The sustained, rapid pace of new capacity additions needed to meet environmental goals and ensure reliability is unprecedented in PNM’s history,” the IRP stated. 

In a report filed March 14, PRC staff recommended that the commission reject PNM’s plan, saying it did not meet the key objectives of an IRP, namely reliability, environmental compliance and affordability. 

“In the three years since the 2020 IRP, PNM’s net load has not changed significantly and it has not filed a notice of material change with the commission,” staff said in its report. “Yet PNM’s 2023 IRP requires an increase in resources over the 2020 IRP of 2,690 MW at an additional cost of $2.7 billion!” 

Even if adjusted for removal of 300 MW of existing resources and a 500-MW increase in the load forecast for 2042, the increase in capacity additions is 1,890 MW, the report said. 

The increase in resources in the 2023 IRP is because the utility postponed the addition of 480 MW of hydrogen-ready combustion turbines to the 2031-2042 time frame, according to the report. 

As a substitute for the delayed hydrogen-ready turbines, PNM is planning additional solar and battery storage — 800 MW and 905 MW more, respectively, compared to its 2020 plan. 

“PNM represents that it takes over three times as much new solar and storage to provide the same equivalent capacity as hydrogen CT capacity,” PRC staff said in the report. 

According to the IRP, the hydrogen-ready turbines may run on natural gas until PNM transitions to a carbon-free portfolio in 2040. 

The PRC staff report said the four-hour battery storage proposed in the IRP is “overbuilt,” creating a risk of stranded costs when longer-duration storage becomes available. 

In addition, the report said, PNM uses an “island” rather than “integrated” approach to its planning, “by its very limited consideration of regional energy markets and an expanded transmission network.” 

Longer Life for Peakers

The report identified a potential solution to some of the issues it raised: extending the Valencia and Reeves gas peaker plants.  

PNM receives about 155 MW of peaking capacity from the Valencia power plant under a 20-year power purchase agreement ending May 2028. Reeves Generating Station, which the utility owns, is scheduled for retirement in 2031.  

“Extending the lives of the Valencia and Reeves gas-peaking facilities prevents overbuilding [and] out-of-control rate hikes and allows time for the development of long-duration storage,” the PRC staff report said. 

O’Connell said much of what staff said in its report “would have benefited from having a response from PNM.” PNM in February filed a response to issues raised by stakeholders, but the staff report was filed in mid-March, just a few weeks before the commission’s vote. 

O’Connell also cautioned against taking “as fact” the resources detailed in the IRP’s most cost-effective portfolio, particularly in later years. For example, geothermal energy could develop into a more prominent resource in New Mexico. 

“It’s something that could play out over 20 years,” O’Connell said of PNM’s future resource mix.  

“The truth of it is the bids that will be received in the [request for proposals] is what’s going to determine the next resources.”

Climate Activists Urge FERC to Reject Results of ISO-NE FCA 18

Climate activists from New England are calling on FERC to reject the results of ISO-NE’s Forward Capacity Auction (FCA) 18, arguing the auction disproportionately favored fossil fuel resources. 

FCA 18 was held in early February and applies to capacity for the 2027/2028 capacity commitment period. The auction procured 31,556 MW of capacity for about $1.3 billion. (See Prices, Renewables Rise in New England Capacity Auction.) 

The auction saw some gains for clean energy resources: Battery storage increased from about 3.5 to 6% of the total capacity procured compared to FCA 17, while solar increased from 3 to 4%. For the second auction in a row, no coal resources gained a capacity commitment, foreshadowing the announcement in March that Granite Shore Power will retire the region’s last coal plant by 2028. (See Last Remaining Coal Resources in New England Set to Retire.) 

However, the majority of the capacity commitments awarded in FCA 18 still went to fossil resources. Natural gas resources accounted for about 44% of the capacity, while oil generators accounted for about 11%.  

In response to these results, activists with the organization No Coal No Gas have submitted comments to FERC arguing the results should be rejected because the auction does not take into account the climate or public health consequences of burning fossil fuels (ER24-1290). 

As the states work to rapidly shift away from fossil fuel generation, “a key barrier we face is ISO-NE’s continued reliance upon outdated modes of decision-making that prioritize short-term financial calculus at the expense of long-term strategic thinking,” said Sonja Birthisel, a member of ISO-NE’s Consumer Liaison Group (CLG) and an environmental scientist associated with the University of Maine. 

The activists also argued that fossil resources often “don’t perform as advertised” during grid stress events. Nathan Phillips, a professor of ecology at Boston University who also is an elected member of the CLG, pointed to ISO-NE’s findings that 36 generators in New England experienced some form of unplanned outage during Winter Storm Elliott, resulting in 2,277 MW of capacity reductions. 

Phillips also wrote that ISO-NE has not tapped into the full potential of demand response resources, which could reduce the need for fossil peaker plants. 

“Demand response is the simplest, most cost-effective and reliable solution to peak demand, which ISO-NE ignores with increasingly deafening silence,” Phillips said, adding that demand reductions could help limit need for additional transmission capacity. (See ISO-NE Prices Transmission Upgrades Needed by 2050: up to $26B.) 

Responding to the protests, ISO-NE spokesperson Matt Kakley noted more than 2,600 MW of demand resources cleared the auction.  

“Demand response can and does participate in all of our wholesale markets,” Kakley said. “Additional participation at the residential level will need to be driven at the state/retail level,” he added, highlighting a New England Conference of Public Utilities Commissioners working group that’s investigating the role of demand response on the grid. 

Regarding emissions, Kakley said ISO-NE “has no jurisdiction by which to assess the environmental attributes of different resources.” 

He added that ISO-NE has “long recommended carbon pricing as a way to account for environmental factors within the wholesale markets,” but said the RTO would need support from the states to have a chance of FERC approval.  

“Thus far, there has not been state support for carbon pricing in the wholesale markets,” Kakley said. 

Environmental organizations made similar arguments in 2023 in opposition to the previous FCA. FERC ultimately sided with ISO-NE and approved the results, writing that the protests were “outside the scope of this proceeding because they do not bear on the sole question here — namely, whether ISO-NE conducted FCA 17 in accordance with its own tariff rules” (ER23-1435). (See FERC Accepts Results of ISO-NE FCA 17.)

NERC Answers IRC Cold Weather Standard Objections

In comments submitted to FERC on April 4, NERC pushed back on the ISO/RTO Council’s objections to its proposed cold weather standard, urging the commission to deny the IRC’s “extraordinary requests” and approve the standard “without further delay.” 

EOP-012-2 (Extreme cold weather preparedness and operations) is under consideration by FERC, having been submitted by NERC on Feb. 16 after its approval by the ERO’s Board of Trustees (RD24-5). If approved, it will replace EOP-012-1, which FERC approved in 2023 with the caveat that NERC must submit a successor within a year to address numerous “undefined terms, broad limitations, exceptions and exemptions, and prolonged compliance periods” before the standard takes effect in October. (See FERC Orders New Reliability Standards in Response to Uri.) 

The IRC submitted a petition March 21 expressing its members’ “united opposition” to approving the standard as currently written. Despite expressing support for the prevention of cold weather-related outages such as those experienced during winter storms Elliott and Uri, the IRC said the ERO’s standard drafting team had left its “most significant concerns … unaddressed” and approving the standard could lead to more reliability issues, additional work for FERC, and great costs for generator owners and the public.  

It asked the commission to remand the standard to NERC and direct the ERO to submit revisions addressing the IRC’s issues within 120 days. (See IRC Urges FERC to Remand NERC Cold Weather Standard.) 

IRC Called Standard Too Generous

In its filing, NERC summarized each of the IRC’s objections and explained why they did not justify remanding the standard.  

A common theme expressed by the IRC was that the proposed standard gave too much latitude to industry on its implementation, which could create auditing difficulties. For example, the standard would specify that freeze protection measures would not “be limited to optimum practices, methods or technologies,” but could include measures “generally implemented … in areas that experience similar weather conditions.” The IRC suggested revising the standard to require measures “that would reasonably be expected to result in effective … performance.” 

Another concern the IRC identified was that GOs could claim an exemption to implementing some freeze protection measures if doing so would “require prohibitively expensive modifications or significant expenditures on equipment with minimal remaining life.” The council said cost issues were outside the scope of reliability standards and the proposed requirement could “invite a ‘race to the bottom’ as [GOs] face economic incentives to keep their compliance costs lower than those of their competitors.” 

NERC said in its response that while the standard drafting team’s priority was to “provide a high bar for generators that operate in cold weather,” members had to balance this with concerns that high costs or technical limitations might cause generators to choose not to operate in cold weather, leading to increased reliability risks. The SDT also felt that GOs should neither be required to adopt “unproven technologies” nor discouraged from implementing “new freeze protection methods as they are developed.” 

“The commission is not being asked in this proceeding to choose among the ‘best’ or most just and reasonable of all potential options, only to assess whether NERC’s proposed definition is just and reasonable,” NERC said.  

The IRC also objected to excluding generators that do not normally operate in freezing conditions from implementing freeze protection measures, arguing that they may be called on to operate during emergency situations, including in cold weather. It asked FERC to order that all units “that may be committed to operate” in freezing temperatures be required to use freeze protection measures. 

NERC replied that “avoiding undue burden on those generating units that are not expected to operate in cold weather,” even though they may be needed in an emergency, is “a fundamental premise of the EOP-012 standard.” The ERO further observed that FERC’s directive approving EOP-012-1 and ordering a new standard specifically quoted the language exempting those units not typically used during freezing weather — along with the fact that they could be used in emergency conditions — and did not demand any changes to it. 

In addition, the IRC criticized NERC on the time provided for freeze protection measures’ implementation in EOP-012-2— which the IRC wanted to shorten from as little as 24 months to a minimum of 12 months — and for required inspections and maintenance, for which the standard does not provide a time requirement.  

NERC said the freeze protection implementation timelines provided are “based on a reasonable and measured consideration of all relevant factors” and that shortening the default timelines could result in additional administrative burdens from entities requesting deadline extensions. The ERO also asked that FERC delay any move to require specific timelines on inspection and maintenance until data is available on the standard’s overall effectiveness. 

“Should NERC’s experience monitoring the implementation of the standard provide factual support for revising the standard, NERC will promptly initiate its standard development process to make any needed changes and to use all the reliability authorities at its disposal to ensure reliability in the interim,” NERC said. “In the interest of reliability, however, entities must begin to implement the important protections this standard will provide without further delay.”

FERC’s Christie: Transmission Can’t be Built Without State Support

The surest way to ensure that transmission is not expanded is to usurp states’ authority, FERC Commissioner Mark Christie said April 4 at WIRES’ Spring Member Meeting in Chicago. 

With the Infrastructure Investment and Jobs Act, Congress directed FERC and the Department of Energy to update their processes on designating National Interest Electric Transmission Corridors (NIETCs) after a federal court curtailed the commission’s backstop siting authority from the Energy Policy Act of 2005. A NIETC designation allows the commission to overrule states that reject lines proposed in the specified area. 

The commission will implement that law because it is a creature of statute, Christie said. But he predicted the changes would have little practical effect. (See DOE Lays out Plans for Designating Transmission Corridors.) 

“The backstop siting authority will last until the point when FERC actually imposes a backstop siting authority on a state that just had a proceeding and found that it was not needed,” Christie said. “That’s as long as it’s going to last because the political blowback is going to be off the charts.” 

While he was on Virginia’s State Corporation Commission, Christie voted to approve more than 100 certificates for transmission lines, from small “wreck and rebuild” lines to the Trans-Allegheny Interstate Line (TrAIL) project, which was the longest regional project built in PJM. That project went through three states, including high-value real estate in Virginia’s Horse Country, where owners did not want it to spoil views of their “10,000-acre” estates, Christie said. 

The opposition was well funded and vociferous, but the line was needed to maintain reliability, he said. 

“And because of the process that we followed and giving the public the opportunity to come in front of their own state body, I think that played a big part in why Virginia politicians didn’t come out in opposition to it,” Christie said. 

If FERC were to overrule a state’s rejection of such a project, all its senior politicians, including its congressional delegation, would oppose it.

“You cannot get stuff built without state buy-in,” Christie said. 

Christie extended the same basic argument to the commission’s Notice of Proposed Rulemaking on transmission planning, the final rule of which FERC could vote on in the coming months. 

“There’s a lot of people running around Congress, ghostwriting letters for congressmen to send to us saying, ‘Well, don’t let the state stand in the way,’” Christie said. “You know, don’t let the states be an obstacle. FERC should just do it. FERC should just impose the cost allocation.” 

He recalled that two of the early, important cases he sat on during his SCC tenure were Dominion Resources’ and American Electric Power’s requests to join PJM. 

“We approved them because we thought regional planning could give us, occasionally, a regional reliability project that would be more efficient than a local project if the facts were there,” Christie said. “And we were willing to let PJM plan those regional projects, but they’re reliability projects.”

The facts are easy to prove for reliability projects, he said; the same can be said for economic projects that make sense as long the benefits outweigh the costs. However, the NOPR (and Order 1000 before it) contemplates a third category: public policy. That is where Christie has some concerns. 

“A public policy project is planned by politicians; [it is] fundamentally different,” Christie said. 

They work in single-state markets, but in RTOs, with multiple states that often have divergent policies, they can lead to problems. 

“If politicians in one state want 100% green energy, that’s fine,” Christie said. “If they want to pay for it. If they’re willing to accept the reliability consequences. That’s fine. But don’t make consumers in another state pay for it, unless they agree.” 

It does not make sense to throw those three categories into a regulatory blender and allocate every type of line across an entire RTO footprint, he added. 

“Even a policy project has reliability benefits,” Christie said. “Well, tangentially it may. You can build a line almost anywhere and get some congestion relief. That doesn’t mean it’s the optimal solution.” 

The way to build transmission projects is to have states buy into them, even when they are incredibly controversial like TrAIL, which is on the same scale of transmission that the NOPR’s supporters most want to see get built. Getting FERC to impose cost allocation on the states if they cannot independently come to an agreement will not work, Christie said. 

“I think that’s a pipe dream,” he added. “I think that’s just totally unrealistic the way things work in America.”

PSEG Plans for 80-year Nuclear Generation in NJ

PSEG subsidiary PSEG Nuclear has told the Nuclear Regulatory Commission it plans to request operating license extensions for its three South Jersey nuclear plants, which would enable the oldest plant to continue running until 2056 and the newest until 2066. 

With NRC approval, the plants, which are central to New Jersey’s clean energy goals, would operate until they are 80 years old — almost double the 42 years that is the average age of U.S. nuclear plants. 

The utility told the NRC in a March 28 letter it expects to seek license renewal for the plants — Salem Generating Station Units 1 and 2 and Hope Creek Generating Station — in the second quarter of 2027. The application would trigger a two-year review and approval process for the plants, which generate 3,468 MW of energy, PSEG said in a statement.   

“This early notification is intended to provide the NRC with time to ensure resource availability when the formal applications are submitted in 2027,” the company said. 

The three plants generated 42% of the electricity produced in the state in 2022 and are key to Gov. Phil Murphy’s (D) goal of reaching 100% clean energy by 2035. Solar projects account for about 8% of New Jersey’s in-state production, and construction has yet to start on any offshore wind projects, so nuclear-generated electricity will be essential to the state’s ability to produce clean energy and cut emissions for years to come. 

The state’s Energy Master Plan says nuclear plants will need to be “retained past current licenses” and predicts that in 2050, nuclear plants will produce 16% of the state’s electricity, compared to 34% generated by solar and 23% produced by offshore wind. 

Charles (Chaz) McFeaters, president of PSEG Nuclear, said the company has “safely generated reliable, always-on carbon-free energy” for five decades. 

“Seeking to renew our licenses signifies our commitment to continuing to contribute to New Jersey’s clean energy future and serving as a vital economic engine for the local community,” he said. 

Aging Plant Inspections

There were 54 commercially operating nuclear power plants in the U.S. in 2023, with 93 reactors in 28 states, according to the U.S. Energy Information Administration.  

U.S. nuclear plants initially are licensed for 40 years and can submit an application to the NRC to renew the licenses 20 years at a time. The NRC has completed 61 applications to extend a license from 40 to 60 years, known as initial license renewals, but has completed just three applications to extend a license from 60 to 80 years, known as subsequent license renewal. 

PSEG’s plan follows the announcement in March that Michigan’s 800-MW Palisades nuclear power plant, which was opened in 1971 and decommissioned in 2022, could become the first nuclear plant in the U.S. to be restarted, helped by a $1.52 billion loan from the federal Department of Energy’s Loan Programs Office (LPO). (See LPO Announces $1.52B Loan to Restart Palisades Nuclear Plant.) 

Diane Screnci, a spokeswoman for the NRC, said the agency’s extensive research on nuclear plant aging concluded that “most nuclear plant aging issues are manageable and do not pose technical issues that would prevent them [from] … operating [for] additional years beyond their original 40-year license period.” 

Each reactor is licensed based on a specific set of requirements, called the plant’s “licensing basis,” she said. “The license renewal review process provides continued assurance that the current licensing basis will maintain an acceptable level of safety for the period of extended operation. The renewed license requires ‘aging management programs’ to monitor and manage the effects of continued operation on certain structures, systems and components.” 

The agency conducts an extensive inspection and oversight program at every plant throughout its life, she said.  

Chizi Odidika, media relations manager for the Nuclear Energy Institute, said planned life extensions for nuclear plants are not unusual. 

“Over 90% of our current nuclear fleet intends to pursue operation for at least 80 years,” she said, adding that “extending their lifespan involves significant considerations and investments, including the development of robust monitoring programs to track the aging of key structures and systems.”  

Federal Nuclear Subsidies

PSEG is the sole owner and operator of the Hope Creek plant and the operator and majority co-owner of Salem 1 and Salem 2 plants, with Constellation Energy the minority co-owner. 

The company’s oldest nuclear plant, Salem Unit 1, came online in 1976 and in 2011 was granted a license extension to continue operating beyond the initial expiration in 2016 to 2036. The utility now plans to ask for an extension to operate until 2056.  

Salem Unit 2, which came online in 1980, obtained an extension to operate beyond 2020 to 2040, and approval of the planned request would continue operations there until 2060. Hope Creek came online in 1986 and obtained an extension to operate until 2046. PSEG will seek a license to operate the plant until 2066. 

PSEG’s announcement comes as the Inflation Reduction Act (IRA) this year begins offering nuclear production tax credits (PTC) to nuclear plant operators. PTCs create a credit of $15/mWh for electricity produced by existing nuclear plants. 

PSEG in November told the New Jersey Board of Public Utilities (BPU) the utility would withdraw from the state zero emission certificate (ZEC) program to pursue the federal tax credits. The New Jersey program provides subsidies to nuclear power plants at risk of closure so they can remain open to generate carbon-free power. It paid $10/MWh. 

The BPU twice awarded ZECs totaling $300 million a year to PSEG, in 2019 and 2022, and the company had filed a notice of intent to seek incentives in the next period, which would run from 2026 to 2029. But the BPU shut down the program after PSEG’s withdrawal because there were no remaining applicants. (See NJ Closes Nuclear Subsidy Process as PSEG Looks to Feds.) 

The ZEC process became contentious in the last period, with the New Jersey Division of Rate Counsel, the state’s consumer advocate, and environmental activists arguing PSEG exploited its market dominance to extract an unnecessarily large payoff and didn’t need the maximum ZEC to keep the plants operating.

Nev. RTO Effort Turns Focus to NV Energy Day-ahead Studies

In studies predicting NV Energy would benefit more from joining CAISO’s Extended Day-Ahead Market than SPP’s Markets+, a key factor is the benefits the utility would lose by leaving the Western Energy Imbalance Market, a consultant said. 

If NV Energy joins Markets+, it would drop out of the WEIM, the real-time market run by CAISO, and join SPP’s Western Energy Imbalance Service (WEIS). 

Leaving the WEIM would create a loss of nearly $100 million for NV Energy, according to John Tsoukalis with the Brattle Group, which conducted the market analysis for NV Energy.  

“So even when you replace that with the gains you see from joining Markets+ and the gains you see by the Markets+ real-time market … it’s not as beneficial as the EDAM cases you see,” Tsoukalis said during a Public Utilities Commission of Nevada (PUCN) workshop April 3. 

Leaving the WEIM would reduce NV Energy’s access to excess renewables from CAISO in real time, and the utility’s prices for real-time sales would fall, according to the study. 

Other WEIM participants also might feel an impact if NV Energy leaves CAISO’s real-time market, Tsoukalis told RTO Insider, although he noted Brattle hadn’t done calculations for other utilities. 

“I would assume the breaking apart of the WEIM would have a negative impact on the other current WEIM [participants],” he said in an email. 

Market Choice Evaluation

The PUCN opened a docket last year to explore ways to evaluate a utility’s choice of a regional market or RTO. (See Nev. Regulators to Weigh Approaches to RTO Membership and RTO, Day-ahead Choice Closely Linked, Nev. Effort Shows.) 

The April 3 workshop focused on cost-benefit studies for market participation; a workshop to discuss different market designs is slated for April 10 at 10 a.m. 

The latest workshop featured presentations on an Energy+Environmental Economics (E3) cost-benefit analysis that was part of the wider Western Markets Exploratory Group (WMEG) study and Brattle’s study for NV Energy, which the utility released last month. (See NV Energy to Reap More from EDAM than Markets+, Report Shows.) 

The Brattle Group study found that joining EDAM would grant NV Energy $62 million to $149 million in annual benefits. Results of the company joining Markets+ would range from a $17 million loss to a $16 million benefit. The study looked at two scenarios in which it joins EDAM and three in which it joins Markets+, calculating benefits expected in 2032. 

In a scenario that Brattle calls the EDAM bookend case, NV Energy and almost all other Western Electricity Coordinating Council (WECC) utilities join EDAM. 

NV Energy’s trading volumes would nearly double in that case, as the utility would serve as a central hub for trading between California and the Southwest and facilitate transfer of low-cost generation from California and the Southwest into Idaho Power and PacifiCorp East. NV Energy’s annual benefit in the EDAM bookend is estimated at $62 million. 

But the utility’s annual benefit would be even higher — an estimated $149 million — in a scenario called Middle View 1. 

That scenario assumes NV Energy, Idaho Power and Seattle City Light join EDAM, along with entities that have announced an EDAM choice, which now includes Portland General Electric. (See CAISO’s EDAM Scores Key Wins in Contested Northwest.) 

In Middle View 1, the Bonneville Power Administration and most of the Northwest’s publicly owned utilities, Puget Sound Energy, and all Arizona BAAs would join Markets+. 

Middle View 1 gives NV Energy access to more resources that are “bottled up” in a smaller EDAM footprint, Tsoukalis said. 

“[During] midday hours in most of the year, you can actually buy power when you need it at almost no cost,” he said. “Whereas in the EDAM bookend case, you kind of have to share that with the Southwest and the Pacific Northwest.” 

Markets+ Scenarios

If NV Energy joined Markets+ rather than EDAM, NV Energy’s generation costs from EDAM participants would rise and trading with those entities would decrease. Instead, the utility would do more trading with Northwest and Southwest BAAs under a Markets+ bookend case. It would gain $16 million annually in that scenario.

If NV Energy joined Markets+ but Idaho Power went with EDAM — in a scenario Brattle called Middle View 2 — NV Energy would lose $17 million annually, as the scenario cuts off a major Northwest-Southwest artery for Markets+. 

“Being in the WEIM alone with almost the full WECC in that footprint is more beneficial for NV Energy specifically than this kind of bifurcated case,” Tsoukalis said. 

Brattle also calculated WECC-wide results for different NV Energy scenarios. 

The greatest WECC-wide benefit, $985 million, was seen in the EDAM bookend case. The least benefit was $682 million in the Middle View 2 case, in which NV Energy chooses Markets+ but Idaho Power goes with EDAM. 

“All of these cases do create for the West as a whole a benefit,” Tsoukalis said. “Even in the cases where things are bifurcated and you get multiple day-ahead markets, the presence of those day-ahead markets does create customer savings relative to the business-as-usual case.”

NEPOOL PC Supports Additional Delay of FCA 19

The NEPOOL Participants Committee voted April 4 to support an additional two-year delay of ISO-NE’s Forward Capacity Auction 19 to buy time for the RTO to develop and implement resource capacity accreditation (RCA) changes and shift the overall timeline of capacity auctions. 

FCA 19 will procure capacity for the 2028/2029 capacity commitment period (CCP), and initially was scheduled for February 2025. The auction previously was delayed by a year in a filing approved by FERC in early January. (See FERC Approves ISO-NE’s One-Year Delay of FCA 19.) The additional delay would push the auction to February 2028, with the related CCP set to begin in June of that year. 

This February, ISO-NE endorsed a major redesign of its forward capacity market. While auctions historically have been held more than three years prior to each yearlong CCP, ISO-NE hopes to adopt a “prompt/seasonal” capacity market, with auctions held just months prior to the CCP, which would be broken up into distinct seasonal periods. (See NEPOOL MC Backs Further Forward Capacity Auction Delay, ISO-NE Moving Forward with Prompt, Seasonal Capacity Market Design.)  

Meanwhile, the RTO is continuing work on its RCA updates, which are intended to better align the capacity values assigned to different resources with the actual reliability benefits the resources provide. (See NEPOOL Markets Committee Briefs: March 13, 2024, NEPOOL Markets Committee Briefs: Feb. 6, 2024.) 

The vote on the additional delay passed with broad support from the PC, though some stakeholders have expressed concern the delay could hurt the development of new resources that rely on capacity market revenues.  

To help mitigate these impacts, ISO-NE will allow new resources expected to be operational by June 2028 but that lack capacity supply obligations to qualify for reconfiguration auctions. 

Extended-term/Longer-term Transmission Planning Phase 2

The PC also voted to support a proposal from ISO-NE and the New England States Committee on Electricity (NESCOE) to create a new process for transmission investments to address long-term transmission needs.  

The process would allow ISO-NE to issue a request for proposals targeting long-term transmission needs at the direction of the states. ISO-NE then would select a preferred solution out of the proposals received, while giving the states the option to proceed with this preferred solution. (See NEPOOL TC Approves Process for States’ Transmission Needs.) 

The costs of selected projects would be regionalized among the states unless NESCOE proposes an alternative cost allocation methodology. For a project to be eligible for selection, expected quantified benefits must outweigh costs.  

The PC also passed a supplemental process that would allow the states to select a proposal even if no project passed the cost/benefit threshold. In this supplemental process, one or more states could agree to cover the costs that exceed the benefits, while the rest of the costs would be regionalized.   

Operations Updates

ISO-NE COO Vamsi Chadalavada said overall demand in March was lower than historical levels due to mild temperatures and increasing behind-the-meter solar production. The monthly peak load was 15,692 MW, which occurred on the evening of March 21. 

Chadalavada noted that ISO-NE expects the eclipse on April 8 to cut solar generation by about 3,600 MW but said the RTO “has simulated this event, and our operators are ready.”

BPA Staff Recommends Markets+ over EDAM

The Bonneville Power Administration on April 4 released a much anticipated staff report that tentatively recommends the agency choose SPP’s Markets+ over CAISO’s Extended Day-Ahead Market (EDAM). 

“We stuck to our evaluation principles and are confident in the analysis and public process that led to the recommendation,” Russ Mantifel, BPA director of market initiatives, said in a statement. “Both markets we are considering honor those principles; however, ongoing concerns with governance and some superior features related to greenhouse gas accounting and resource adequacy, among others, led to staff’s preference for Markets+.” 

The staff recommendation, the product of a public process the federal power agency kicked off last July, should come as little surprise to electricity sector stakeholders who have closely followed the growing competition between Markets+ and EDAM to bring a more organized electricity market to the West. BPA was an important contributor to the development of EDAM, but it has been a central participant in the intensive — and expedited — stakeholder process to design Markets+, including the market’s governance structure. 

But the staff report, and an accompanying letter by BPA Administrator John Hairston, also made clear the recommendation is not etched in stone. 

“This is not a final decision, nor is it an endorsement of one market option over another. Rather, it is intended to provide greater insight into the analysis of Bonneville staff and their recommendations based on information gathered to date,” Hairston said in the letter. 

Along with the market recommendation, BPA also released a “preliminary legal assessment” describing the agency’s authority under federal law to join a day-ahead market. The assessment considered multiple factors, including the business case for participation, the agency’s obligations to preference customers, and its environmental responsibilities with respect to operation of its dams. 

The legal assessment notes that the Energy Policy Act of 2005 grants federal utilities the right to join transmission organizations, including RTOs. The assessment points out that Markets+ and EDAM would be “less restrictive” than an RTO because BPA “would retain substantial control over its transmission assets, and its balancing authority area responsibilities would be preserved.” 

“While the development of a day-ahead market is not an RTO, it is reasonable to conclude that Congress contemplated federal utilities would be authorized to participate in subcomponents of an RTO like a day-ahead market as part and parcel of that express authority,” the assessment found. 

‘Important Differences’

In developing the market recommendation, BPA staff considered eight evaluation principles, including: statutory, regulatory and contractual obligations; service reliability for BPA customers; resource adequacy frameworks to maintain system reliability; business rationale; consistency with BPA’s 2024-2028 strategic plan; governance; commercial and operational impact of day-ahead market participation on customers; and handling of greenhouse gas emissions. 

Governance has been a top concern for BPA as it contemplates joining a day-ahead market that could eventually evolve into an RTO. For the agency, CAISO’s governance, which is subject to oversight by California state officials, has been a significant hurdle for joining EDAM and a point that heavily favors Markets+. 

“Paramount to Bonneville’s participation in any day-ahead market is the requirement for independent market governance that is not obligated to any single state, entity or trade association,” the staff recommendation said. “Bonneville staff believes that independent governance will ensure that decisions affecting the market are made with consideration of the interests of all market participants.” 

Staff said it saw “important differences” between Markets+ and EDAM in this area, pointing to differing approaches to stakeholder processes as well as governance. 

“Bonneville staff believes that Markets+ has developed a structure and process that is more likely to result in equitable market outcomes and fair consideration of Bonneville’s interest,” the report said. “The structure of the Markets+ Participants Executive Committee (MPEC), work groups and task forces that developed the market design and initial tariff provided all participants an equal opportunity to weigh in on decisions.” 

The BPA report said the Markets+ governance and processes “supported collaboration and negotiation” to help achieve consensus on issues, allowing the agency “to propose and obtain consideration of its statutory and contractual obligations” during development of the tariff. 

BPA staff complimented the Markets+ work group processes for being “publicly accessible” and for considering views of utilities, states and independent organizations. 

They also noted that SPP’s staff have offered technical support and other facilitations “while respecting the decision-making roles of market participants.” 

“As Markets+ transitions from phase 1 to phase 2 and ultimately to an operational market, Bonneville staff expects the MPEC, work groups and task forces to maintain the same level of decision-making and collaboration that crafted the tariff,” the BPA report said. 

BPA staff contrasted SPP’s approach with what they called CAISO’s “staff-driven model.” 

“Bonneville staff acknowledge the CAISO’s efforts to develop a more participatory stakeholder engagement process. Bonneville appreciates and respects the professionalism and expertise that CAISO staff routinely display in their stakeholder process, but Bonneville staff believes the process is still lacking in stakeholder leadership and engagement in policy and implementation development, evaluation and decision processes,” the report said. 

On governance, BPA staff said CAISO’s model “has presented challenges in resolving contentious regional issues” and that the agency has observed “that EDAM governance presents real problems for Bonneville’s participation in a day-ahead market and could result in unbalanced outcomes, as it continues to operate under provision of California law. 

The report notes that CAISO’s Board of Governors is appointed by California’s governor “with obligations to California ratepayers embedded in California laws and policies.” The ISO’s “dual responsibilities” of serving California load and operating day-ahead and real-time markets “has resulted in Bonneville, and consequently its customers in the Pacific Northwest Region, being at a competitive and governance disadvantage,” the report contends. 

BPA staff acknowledged the efforts of the West-Wide Governance Pathways Initiative to create a more independent governance structure for a single Western market that would expressly include California and rest on the platform of EDAM and CAISO’s Western Energy Imbalance Market. 

“Bonneville’s view is that achieving the objective of Pathways likely requires modification of California legislation, which has not gained traction in the past,” the report said. “Bonneville is tracking the effort’s legal analysis for indicators regarding the viability and potential timeline for governance updates. Throughout its decision-making process, Bonneville will continue to consider the progress of Pathways.” 

“I don’t anticipate, at this point in time, that we’ll get more involved [in Pathways] than we are right now,” BPA’s Mantifel said during an April 4 press briefing. “We will be evaluating anything that comes out of the Pathways Initiative as part of our ultimate decision, so when we do make the decision later this year, we will take into account any governance changes that have either been realized or proposed as a result of the Pathways Initiative.” 

SPP Wins on RA, GHGs

Markets+ also won favor with BPA staff on the issue of resource adequacy based on the market’s requirement that eligible participants also join the Western Power Pool’s Western Resource Adequacy Program (WRAP), which is operated by SPP. 

“WRAP has become the dominant resource adequacy program outside of California,” the BPA report said. “The EDAM proposal does not propose a uniform adequacy metric or require EDAM entities to participate in a resource adequacy program. Bonneville staff supports and prefers the clear and consistent requirement that all Markets+ [load-responsible entities] must participate in WRAP, which better supports regional reliability.” 

While California utilities are subject to a state-mandated RA requirement, other EDAM participants outside California can participate in the WRAP but are not required to join an RA program, BPA staff noted. 

“The EDAM proposal’s lack of a common resource adequacy metric makes it difficult to assess whether the footprint as a whole will be resource adequate in the planning horizon. Further, failure to adequately plan in advance to meet demand by the day-ahead time frame could undermine the ability of the market to find adequate supply to serve load in the short day-ahead time frame,” the report said. 

BPA staff also favor the way Markets+ will handle the tracking and accounting of greenhouse gas emissions, an issue of specific concern for agency customers in Washington state, which last year adopted a cap-and-trade system to price carbon. While both Markets+ and EDAM are designed to attribute specific resources to states with GHG pricing, BPA staff said SPP’s design offers more assurance that energy from the federal hydro system will be attributed to BPA’s Washington customers who have contracted for that power. 

“In contrast, CAISO’s design would attribute the federal system to Washington only when it is the most economical solution for the entire market footprint,” BPA staff said. “This outcome of CAISO’s design would adversely impact Bonneville because, at times when the system is not attributed to Washington, Bonneville may not be able to recover the difference between the price it receives for system resources and the cost it pays for load in the GHG area.” 

BPA staff also preferred the Markets+ approach to transmission congestion rent, saying it “better models physical congestion in Bonneville’s transmission system, allocates congestion rents according to constraint-level congestion and allocates congestion rents directly to long-term transmission right holders, which provides consistency for transmission customers across the entire footprint.” 

BPA plans to issue a draft decision on its market choice in August, followed by a final decision late in the year, likely in November. In the meantime, it will hold additional workshops on the issue this summer. 

Reactions

Stakeholder reactions to the BPA recommendation were mixed, if predictable. 

“SPP is very pleased to hear of BPA’s staff recommendation to join Markets+,” RTO spokesperson Meghan Sever said in an email to RTO Insider. “BPA has been an active participant in Markets+ development, and we look forward to continued collaboration as we work to build a Western energy market that provides environmental and financial benefits and enhances electric reliability in the Western Interconnection.” 

“We respect BPA’s public process and appreciate our continuing collaborative relationship on the broad set of Western electricity issues, as well as BPA’s partnership and successful participation in the Western Energy Imbalance Market,” CAISO said. 

Opponents of BPA’s “leaning” in favor of Markets+ offered stronger words. 

The Northwest Energy Coalition (NWEC), which has strongly advocated for a single Western market, once again advised BPA to ease up on its timeline for selecting a market. 

“NW Energy Coalition and our allies urge BPA to keep an open mind and continue to do comprehensive analysis before making a decision,” NWEC said in a statement, noting that EDAM, which has already been approved by FERC, builds on the WEIM, a market in which BPA already participates. 

“The WEIM already covers more than 80% of the Western region and has provided more than $5 billion in customer benefits. It is no exaggeration to say the WEIM has provided a crucial contribution to keeping the lights on during extreme weather events, including the mid-January freeze in the Northwest,” NWEC said. 

“This decision makes clear that the Bonneville Power Administration cares more about political control than its customers, residents of the Northwest, or endangered salmon and steelhead,” Mitch Cutter, salmon and energy strategist at the Idaho Conservation League, said in a statement. “A single regional market could help save ratepayers money, decarbonize the grid and reduce the Northwest’s dependence on salmon-killing hydropower. Instead of heeding its mission and statutory obligations, BPA seems hellbent on joining Markets+ and fragmenting the West when unity is most needed.” 

Advanced Energy United Executive Director Leah Rubin Shen said it was “exciting” that BPA staff determined it would be legal and beneficial for the agency to join a day-ahead market, but she said joined “energy industry and policy leaders throughout the region — including the governors of Washington and Oregon — in finding the recommendation about which market to join premature.” 

“This is a very dynamic landscape that is rapidly changing. BPA’s own modeling shows their customers and partners will benefit most from being in the same market as California, and there is a robust effort underway — the West-Wide Governance Pathways Initiative — to resolve BPA’s primary objection regarding independent governance,” she said. 

‘Absolutely Critical’

BPA’s final decision will carry significant weight in the Northwest, where it operates 15,000 circuit miles of transmission — or 70% of the regional system — and is the largest power provider, controlling 17,500 MW of generating capacity. 

But a final decision in favor of Markets+ could leave the agency at risk of hemming itself into a relatively small market with limited links to other potential participants, depending on the choices of neighboring balancing authorities. 

On that front, EDAM has already won commitments from significant players in the Northwest, including PacifiCorp, whose six-state territory extends into the Intermountain region, and Portland General Electric, Oregon’s largest utility by customer base. Publicly owned Seattle City Light, which has been deeply involved in the Pathways Initiative and is listed among its top funders, is expected to follow suit. (See CAISO’s EDAM Scores Key Wins in Contested Northwest.) 

Sources have told RTO Insider that decisions by Idaho Power and NV Energy will be vital for determining how markets take shape in West but especially important for the functioning of Markets+, which has its strongest support in the Pacific Northwest and Arizona — areas separated by more than a thousand miles and a lack of transmission links. 

Signs point to both joining EDAM, although that’s still uncertain. 

Idaho Power offered the clearest signal last month in a letter to CAISO saying it is leaning toward joining EDAM after determining that the market offers the greatest value for its customers. The Boise-based utility has also recently partnered with the ISO to fund a Nevada transmission line designed to increase transfers of renewable energy between Idaho and points to the south, opening up the potential for more energy sales into the Southwest. 

And while NV Energy has been more guarded about its direction, a recent Brattle Group study found the utility would realize significantly greater financial benefit from participating in EDAM than Markets+. The Nevada utility’s choice will be pivotal for either market, given the central location of its transmission network and its role in facilitating transfers among WEIM participants. (See NV Energy to Reap More from EDAM than Markets+, Report Shows.) 

“Where it looks like we’re going to go right now — if Markets+ succeeds in moving forward with a lot of support across the West — is a Northwest zone and a Southwest zone with no direct connection from transmission,” Fred Heutte, senior policy associate at NWEC, said in an interview in February. “It’ll have to transfer power across the grid of other entities that are not in Markets+.” 

Asked during BPA’s press briefing about the weight of such geographical factors in its final decision, Mantifel called them a “major factor,” but he also noted that while the agency’s financial benefits would be “sensitive” to the market footprint, it has not identified any “bright line at this point in time that would automatically shift our decision.” 

Asked whether the governance issue would outweigh financial benefits, Mantifel said: “I would say governance occupies a pretty equal spot in our evaluation. Yeah, governance is an absolutely critical issue for Bonneville in making this decision.”

Robb, Cancel Review Reliability Landscape

In their annual media call April 4, NERC CEO Jim Robb and Electricity Information Sharing and Analysis Center (E-ISAC) CEO Manny Cancel said that while the reliability landscape continues to grow more complex, the ERO Enterprise is focused on grappling with any problems that might emerge. 

The call covered a wide range of topics, including the in-progress Interregional Transfer Capability Study (ITCS) and last year’s GridEx VII security exercise, the report for which NERC also released this week. (See NERC Flags Communication, Coordination in GridEx VII Report.) 

In his opening remarks, Robb said the ERO is “about halfway through” its three-year plan for 2023-2025 and that he feels “very good about where we are” and what it has accomplished so far. Nevertheless, he also acknowledged that NERC’s agenda has become full over the last year, with orders from FERC on inverter-based resources and cold weather standards and Congress’ mandate for the ITCS, which must be submitted to FERC by December. 

Because of the new assignments, particularly the ITCS, NERC has had to reconsider its work plan priorities, and some of the activities that were planned for 2023 and 2024 could not be completed in the original time frame, Robb said. In addition, some of the new hires who were intended to work on the ERO’s work plan priorities were shifted to the ITCS. 

“We did go back through our priorities and talked with the board and pushed a few of them off to this year and beyond,” Robb said. “One of the major ones we wanted to do was a comprehensive assessment of market rules and how they do — or in some cases, don’t necessarily — support reliability going forward. We decided that was something that was important to be done, but not as urgent as some other things.” 

Robb emphasized that NERC has focused on making sure its added responsibilities, like the ITCS, don’t result in unexpected financial burdens for the registered entities that ultimately fund the ERO through its assessments. The added expenses for 2023 and 2024 were largely met by using the organization’s financial reserves, and the CEO added that “a few things have broken our way” concerning the ERO’s investments that have allowed it to “absorb the work.” 

Robb also said that as the ERO works on next year’s budget, it has made a commitment not to “surprise [stakeholders] with anything next year” in terms of major financial deviations from the three-year plan. 

E-ISAC Monitoring Active Threats

Cancel noted that the E-ISAC — which celebrates its 25th anniversary this year — has seen “significant ramifications” from global geopolitical issues such as Russia’s invasion of Ukraine and Israel’s military actions in Gaza, along with the ongoing tensions between Taiwan and China. These have manifested in a “dramatic increase in malicious cyber activity.” 

The E-ISAC continues to view China as a “top cyber threat,” Cancel said, citing the Volt Typhoon hacking group that CISA said this year had been actively infiltrating U.S. infrastructure operators for at least five years. (See CISA Highlights China Threat in 2024 Priorities Report.) However, Russia, Iran and North Korea also “continue to demonstrate advanced capabilities” to undermine U.S. infrastructure through vulnerabilities on electronic networks. Cancel said these threats demonstrate the need for vigilance and effective internal network monitoring. 

Physical security threats remain a top concern for the E-ISAC as well, with Cancel noting the organization reviewed more than 2,800 physical security events in 2023. He added that this number did not represent a “substantial increase beyond the elevated threat that started [in] 2022.” Cancel also observed that about 3% of the physical security incidents in 2023 affected the grid, but none led to cascading outages. The most serious incidents involved ballistic damage, theft, intrusion, tampering and vandalism. 

Cyber and physical attacks were both part of the plan for GridEx VII, which Cancel noted involved 15,000 individual participants from 252 registered organizations in the two-day distributed play portion and 230 individuals in the executive tabletop. Cancel attributed the drop in participating organizations — with last year marking the smallest number of groups since GridEx II — to changes in “the way we count the participants,” but he said the number of individual attendees represented a significant achievement for the event. 

“Fifteen thousand people across the U.S. and Canada … spent two full days participating. That’s quite a compelling statistic,” Cancel said. “And on the executive tabletop, we’ve seen no decrease there. We continue to get the CEO participation across the electricity sector in the United States and Canada, and I’m also very pleased that we get the appropriate leadership from the federal governments there as well.”

DOE’s Final Transformer Efficiency Rules Seek to Ensure Stable Supply Chain

The U.S. Department of Energy on April 4 finalized energy efficiency standards for distribution transformers to increase grid efficiency and save $824 million annually. 

The congressionally mandated final standards give the industry an extra five years to comply. DOE said it adjusted them based on significant feedback from the industry and others after issuing its proposal last year. The longer time frame will give the industry time to ramp up production of grain-oriented electrical steel (GOES). 

“The regulatory process can work, and this final rule shows just that by reflecting feedback from a broad spectrum of stakeholders,” Energy Secretary Jennifer Granholm said in a statement. “Ultimately, it will be a piece of the solution, rather than a barrier, to help resolve the ongoing distribution transformer shortage and keep America’s businesses and workers competitive.” 

The final standards can primarily be met with GOES, most of which will be manufactured in the U.S., according to the department. Another small subset of new transformers can be manufactured with amorphous alloy, also expected to be manufactured domestically. 

There are more than 60 million distribution transformers around the country, DOE said. 

Efficiency improvements for transformers will cut wasted energy, saving $14 billion and cutting 85 million metric tons of CO2 emissions over 30 years, DOE estimates. The 30-year energy savings total 4.6 quadrillion BTUs, a savings of 10% compared to current products. 

The initial proposal was going to shift the market to 95% of transformers being made from amorphous alloy, but the final standard can be met if 75% of transformers are made with GOES. The final rule also extends the compliance deadline from three to five years. 

The standards are expected to protect the domestic supply of core materials used to build the transformers, increasing supply-chain resilience and preserving manufacturing jobs in Pennsylvania and Ohio, according to the department. 

“I engaged directly with Secretary Granholm and the Biden administration to ensure Pennsylvanians’ concerns about the proposed rules were heard, and I want to thank them for making sure the final rule will allow for Butler Works to continue its existing line of steel production in Western Pennsylvania, while supporting upgrades that will help spur innovation, protect jobs and reduce carbon emissions from the plant,” Pennsylvania Gov. Josh Shapiro (D) said in a DOE statement. 

The standards will significantly cut energy use by transformers, but they miss the chance for much larger savings, said the American Council for an Energy Efficient Economy. The final standards will save only one-third as much energy as the proposed standards would have. 

“These standards significantly reduce energy waste, but they leave much bigger savings on the table,” Andrew deLaski, executive director of ACEEE’s Appliance Standards Awareness Project, said in a statement. “Passing up the savings that could have been achieved has a real cost for consumers, businesses and the climate.” 

The GridWise Alliance said it was still reviewing the final rule, but it said the new framework will ensure that utilities can continue to make investments essential to maintaining the security and reliability of the grid. 

The country is still experiencing a critical shortage of distribution transformers, with the lead time for procuring some types close to two years, GridWise said. The original standard could have exacerbated that shortage, but DOE recognized the industry’s concerns. 

“I want to thank DOE for considering the challenges facing the grid industry and for listening to stakeholders in adapting the final rule to provide more certainty to the market for distribution transformers,” GridWise CEO Karen Wayland said. “Our GridWise members look forward to working with DOE to address the transformer shortage in the short term and in continually improving the efficiency of the electric grid over the long term.” 

Louis Finkel, the National Rural Electric Cooperative Association’s senior vice president of government relations, agreed that the final rule is much improved over the proposal. 

“The final rule provides stability for most of the market while affording a more gradual shift toward tighter efficiency standards for transformers used to meet larger commercial and certain electrification loads,” Finkel said. “We will work closely with our members, manufacturers and suppliers to ensure implementation does not further disrupt an already strained supply chain.”
